InsideClimate News' Lisa Song notes that US EPA's website had originally shown 1,149,460 gallons of oil recovered from the 2010 Enbridge spill near Kalamazoo, Michigan.

Explosions from ammonium nitrate fertilizer, like the one in West, Texas that killed 15 people in April 2013, are only one of many hazards posed to communities from dangerous materials under the purview of EPA and other agencies. Toxic inhalation hazards could kill tens of thousands of people if released in crowded areas. Here are several tools to help you find local facilities that handle toxic, explosive, flammable, corrosive, and otherwise hazardous materials.

A fatal November 30, 2012, collapse of part of a coal-slurry impoundment in West Virginia served as a reminder of safety issues that may not be adequately regulated in some states and localities. You can locate local coal-slurry impoundments and information on their status with an online public database.

After wasting billions of taxpayer dollars on a non-working program aimed at protecting the US public from biological attack, the Department of Homeland Security and Centers for Disease Control may be refusing to give documents on the program to House Energy Committee investigators.
